- Throw It In!: First editions of the book had Aishling's diary portions upside down. This was apparently because the manuscript was dropped and presented that way, so the publishers thought it was intentional.
- Unintentional Period Piece: There's a complete lack of cell phones among the teenagers, immediately dating the book to the 90s. Aishling also refers to "fourpence", showing that it was published before Ireland adopted the Euro in 2002. The lack of social media is a giveaway too; for example Cindy would probably discover that Robbie knew Aishling from posts on his Facebook. Alva is also a fan of Boyzone, who had their heyday in the 90s. Bob and Aishling reference the film of Sense and Sensibility, which was released in 1995, and it's said that Margaret and Philip had to get their divorce legalised in the UK - as Ireland hadn't legalised divorce until that yearnote . Margaret's reason for marrying Richard - fear that Philip might get a conservative judge to declare that he get custody of Alva - could only be plausible in the 90s. In the 2000s the Irish courts became rather infamous for ruling in favour of the mother.
- What Could Have Been: The story was originally going to be entirely from Cindy's POV. However Siobhan Parkinson felt that once she'd finished, she felt a bit sorry for the stepfamily and how nasty Cindy was towards them. Thus she came up with the Perspective Flip with Aishling's diary as well.
